With the above-described configuration, when the attaching / detaching portion 30 and the auxiliary attaching / detaching portion 35 are rotated around the rotation shaft 41, the entire transporting device 3 integrally rotates around the rotation shaft 41. Components such as the guide screw 51 and the guide rod 52 for moving the auxiliary attaching / detaching portion 35 up and down do not hinder the rotation of the attaching / detaching portion 30 and the auxiliary attaching / detaching portion 35. It can be rotated substantially one round.

Further, since the auxiliary attaching / detaching portion 35 is attached to the attaching / detaching portion 30 by the connecting member 6, the auxiliary attaching / detaching portion 35 can be detached from the attaching / detaching portion 30 together with the connecting member 6, and the auxiliary attaching / detaching portion 35 is mounted. The auxiliary attachment / detachment unit 35 can be attached to the attachment / detachment unit 30 via the coupling member 6 on an autochanger that has not been used.

The moving section 55 of the auxiliary attaching / detaching section 35 removes the second moving section 5b from the moving section 5 of the attaching / detaching section 30.
In this configuration, a second gear 51e is attached instead of the first gear 51a.
Since it is shared with the components of No. 0, the attaching / detaching portion and the auxiliary attaching / detaching portion are integrally formed, so that the manufacturing cost can be reduced as compared with an auto changer in which the auxiliary attaching / detaching portion cannot be removed.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the structure shown in the accompanying drawings.

As described in detail above, in the case of the autochanger according to the first aspect of the present invention, the rotating shaft is provided at the center of the storage shelf and the drive device arranged in an arc or a circle, and the rotating shaft is separated in the axial direction of the rotating shaft. A pair of rotary tables are arranged, and both rotary tables are integrally rotatable about the rotary shaft, and an attaching / detaching portion for attaching / detaching a removable recording medium is provided along a guide screw arranged between the rotary tables. Movable, and in accordance with rotation of a rotary shaft disposed between the rotary tables in parallel with the guide screw, a holding portion for holding the recording medium can be moved in a direction intersecting with the axial direction of the rotary shaft. By rotating the rotary table, the portions used for transporting the recording medium, such as the detachable portion, the guide screw, and the rotary shaft, are rotated integrally with the rotary table. Thereby Therefore, without being disturbed rotation of the rotary table by these, it can be rotated over substantially around the detachable portion around the rotational axis.

In the case of the automatic changer according to the second invention, an auxiliary attaching / detaching portion having a holding portion for the recording medium is attached to the attaching / detaching portion, and the holding portion on the attaching / detaching portion side is rotated by the rotation of one of the rotating shafts. By moving the holding portion on the auxiliary attaching / detaching portion side in a direction intersecting with the axis length direction of the rotating shaft in accordance with the rotation of the other rotating shaft, the one attaching / detaching portion is moved. The auxiliary detachable portion can be added to the autochanger having the portion, and the auxiliary detachable portion can be detached from the autochanger having the detachable portion and the auxiliary detachable portion. Therefore, the auxiliary detachable portion can be attached or detached as necessary. .

In the case of the automatic changer according to the third aspect of the invention, when one of the rotary shafts rotates, the first gear of the attaching / detaching portion in which the protrusion is engaged with the groove of the rotary shaft rotates, and the first gear rotates. A guide in which the intermediate gear meshing in one gear section rotates, the cross gear meshing in one gear section rotates with the other gear section of the intermediate gear, and the other gear of the cross gear meshes with the other gear section. When the screw rotates, the holding portion to which the nut screwed to the guide screw is attached moves along the guide screw. Thus, the holding portion on the attaching / detaching portion side is moved in a direction intersecting with the axial length direction of the rotary shaft.

When the other rotary shaft rotates, the second gear of the auxiliary attaching / detaching portion whose projection is engaged with the groove of the rotary shaft rotates, and meshes with the second gear at one gear portion. The intermediate gear that rotates, the cross gear that meshes with the other gear part of the intermediate gear in one gear part rotates,
The guide screw with which the other gear of the cross gear meshes rotates, and the holding portion to which the nut screwed with this guide screw is attached moves along the guide screw. In this way, the holding unit on the auxiliary attaching / detaching unit side is moved in a direction intersecting the axial direction of the rotating shaft.

Therefore, by disposing the intermediate gear at a position where it can be engaged with either the first gear or the second gear, it is possible to selectively attach the first gear or the second gear, and to attach or detach the auxiliary gear or the auxiliary attaching / detaching part. The present invention has excellent effects such that any of the parts can be configured, many parts of the detachable part and the auxiliary detachable part can be shared, and the manufacturing cost can be reduced.
